Filbert orchard nut production increases dramatically after the size of the tree increases, especially when heavily fertilized. The nut from the Filbert (Hazelnut) Tree provided a unique nut food source. There are many brands of nuts available in the supermarket, and the Filbert is very expensive at the grocery store, but can be grown inexpensively with very little maintainance in your garden. The Filbert (Hazelnut) Tree is also called hazelnut in European communities and are one of the popular nuts found under the Christmas tree. The Filbert is available on store shelves in the Fall, and you must plant more than one tree for cross pollination.

The leaves of the Filbert Tree are medium green in color and very vigorous, sometimes growing 5-6 feet per year. As the flowers of the Filbert Tree develop and are pollinated, the nuts begin to swell and grow rapidly during the Summer. The Hazelnut is often eaten fresh, roasted or in confectionery and baking trades. In orchard conditions the Filbert (Hazelnut) Tree is preferable since multiple stems interfere with mechanical collection at harvest time, but the bush form is often preferable for the homeowner or backyard gardening since the nuts are easier to pick from a bush. The Filbert grows from Newfoundland south to Florida, and it grows into a bush in the North but into a small tree in the South.
